South Pacific Breweries was floated as a company in 1952 by a group of local entrepreneurs in Port Moresby. South Pacific Lager is SP Brewery's mainstream brand. It was launched in 1952. It is in 330 ml bottle and can and contains 4.5% alcohol. It is packed in cartons of 24 bottles, 12 and 6. The cans are only packed in 24s. This brand is also in 30 litre keg.

Since being involved in 2005 with rugby union, SP Brewery has supported the 2007 South Pacific Export Regional Satellite Seven's, 2007 PNG Sevens, the 2009 Port Moresby Seven's and more recently the NGI Seven.

"We at SP Brewery are certain that rugby union will continue to grow to become a dominant sport in Papua New Guinea and what better way for us to assist through our premium beer, South Pacific Export Lager," said their General Manager.
